INK-WELL.

SPECIFICATION forming part of Letters Patent No. 726,195, dated April21, 193. Application filed December 31, 1902. Serial No. 137,311. (Nomodel.)

To @ZZ whom it may concern):

Be it known that I, GUsTAv J. SENGBUsoH, a citizen of the United States,residing at Mill waukee, in the county of Milwaukee and State ofWisconsin, have invented new and usefulV Improvements in Ink-Wells, ofwhich thefolf lowing is a specication. l p

My invention relates to new and useful improvements in ink wells orholders, andv relates more particularly to devices of this charfacterhaving automatic means forsupplying ink to a pen when the same isinserted thereinto.

The invention is an improvement upon that shown and described by me inan application filed November 1, 1902, Serial No. 129,732; and itsobject is to simplify the construction of the well, whereby the same maybe more readily manufactured and: be rendered less expensive.

A further object of the invention vis to provide a float feed controllerand stopper which prevents the admission of dirt or dust to theink-holder and obviates the evaporation of ink contained within thedevice.

The invention consists in the novel construction and arrangement of theseveral parts, which will be more fully hereinafter de;

scribed and claimed. f

In the drawings, Figure 1 is a side eleva-vv tion of myimproved ink-welland showing in dotted lines the interior portions thereof. Fig. `2 is acentral vertical section therethrough, and Fig. 3 is a section on line 33 of Fig. 2.

Referring to the figures by numerals of reference, 1 is a receptacle,preferably formed of glass and having a large aperture 2 at the topthereof, while a recess 3 is formed at the center of -the bottom of saidreceptacle. This I cally upon the ribs within neck 6.

these' ribs, as well as the ribs in casing 4, serve to guide ay floatlO,arranged within the lcasing 4 and neck. This float is preferably formedof hard rubber and comprises a cylindrical body 11 and a stem 12,extending upward therefrom and adapted'to move'vertip A gasket 13 isinterposed between the casing 4 and the side of recess 3 and serves toretain said cas- 'ing in properl position within receptacle l and alsoprevents the escape of the contents of the casing at points between itand the walls of recess 3. Air-inlets 14 are formed within the upper endof neck 6, and a vent 15 is aryrangedwithivn one side of casing 4 at apoint in horizontal alinement with the lower surface of oat l0-when saidfloat is in its normal or raisedrposition.

Whenthe ink-well is to be used, the cap 8 Vis removed and ink pouredinto the receptacle 1. It will flow from the same through the vent 15into casing 4 and the air will be forced outward thereby between theribs 5. As the receptacle 1 and casing 4 lill, float 10 will be carriedupward until the top of body l1 thereof contacts with the upper end ofcasing 4, when the upward progress of the contents of the ink-wellthrough the casing 4 and its neck 6 is prevented. When a pen is pressedinto contact with the upper end of stem l2, the body 11 of the float ismoved .downward with said stem, and as the vent 15 is arrangedV withinone of ribs 5 it will be promptly closed and the ink within casing 4will be forced upward between ribs 5 and over the top of stem 12. Whenthe float is released, itwill by reason of its buoyancy return to itsnormal position and that portion of ink which has been withdrawn fromcasing 4 will be promptly replaced by a .portion of theink outside ofthe casing, thesame passing through the vent 15 as soon as the same isopened. The air-inlets 14 prevent the formation of a vacuum. ,Y y

In the foregoing-description I have sho-Wn the preferred form ofmyinvention; butI do not limit myself thereto, as I am aware thatmodications may be made therein without departing from the spirit orsacrificing the advantages thereof, and I therefore reserve foo theright to make such changes as fairly fall within the scope of myinvention.

Having thus described the invention, what is claimed as new is 1. In anink-well, the combination with a receptacle having a recess in thebottom thereof; of a casing having an inlet and open at its lower end,means for supporting said end of the casing within the recess in thereceptacle, guide-ribs within the casing, and a float arranged withinthe casing and between the ribs and adapted when depressed to close theinlet to the casing.

2. In an ink-well, the combination with a receptacle having a recess inthe bottom thereof; of a casing having an inlet thereto and having itslower end open, means for supporting and sealing the casing within therecess, a neck communicating with the casing, ribs within said casingand neck, a iioat within the casing and neck and adapted to bear uponthe ribs therein, said float being adapted when depressed to close theinlet to the casing, and air-inlets in the neck and opening into thereceptacle.

3. In an ink-well, the combination with a receptacle having an inletthereto and a recess in the bottom thereof; of a casing having its lowerend open, means for securing and sealing said end of the casing withinthe recess, a neck upon the casing having inlets communicating with theinterior of the receptacle, ribs within the casing and neck, a floatwithin said casing and neck adapted to bear upon the ribs, and an inletthrough one ot the ribs in the casing and communicating with theinterior of the receptacle, said inlet being adapted to be closed whenthe float is depressed.

In testimony whereof I ax my signature in presence of two witnesses.

GUSTAV J. SENGBUSCH.
